I’ve been wanting to print some of the geared items on Thingiverse for a while. With Valentines day coming up it seemed like an excellent opportunity to try out the Screwless Heart Gears by Thingiverse user Emmett. After reading the assembly instructions the heart came together quite nicely with the help of a hot air gun to help let the printed pins slide in easily.

Completed!

I found it easier to assemble the larger gears first. It allowed me to better align and mesh the smaller gears.
